We wrote the year 1977 when Texas Instruments introduced with the TI-1700 DATACLIP a calculator shaped like a ruler. Within one year both Canon and Toshiba responded with the Ruler-8 resp. this LC-850M.
Dismantling the Toshiba LC-850M reveals a standard design based on the Toshiba T3567 single-chip calculator circuit introduced together with its sibbling T3566 located in the TI-1790 Datachron.
